Build muscle with every set counted
Muscle grows from enough hard sets, spread across the week, with more weight or reps over time. Liftsmith counts your weekly sets per muscle and plans the next workout to fill the gaps.

Volume you can see
Every hard set counts toward the muscles it trains: fully for the main movers, partly for the helpers. Advanced stats (Pro) show each muscle's sets this week against a sensible range, so you know if your back is getting 6 sets or 16. See how many sets per week to build muscle.
The 3D recovery map (Pro) shows which muscles are fresh and which are still recovering, and the planner trains the fresh ones first.
Splits that adapt
Pick push pull legs or an upper lower split and Liftsmith fills each day with exercises for that day's muscles, skipping any that haven't recovered (Pro). Or build your own routines and let the app set the weights.
- Double progression: add reps across the range, then add weight
- Drop sets and rest-pause sets in a tap during rest, and supersets in your routines
- 300 exercises with 3D demos, including cables and machines
- Mark muscles as a priority to give them more sets
Your physique, tracked
Log body weight, body fat and tape measurements for nine sites, and keep progress photos on your phone. A coach's note speaks up when weight drops faster than 1% a week or body fat creeps up.
Questions
- How many sets per muscle should I do?
- Most people grow well on about 10 to 20 hard sets per muscle a week, split over two or more sessions. Start near the low end and add sets if a muscle lags.
- Can I focus on one muscle?
- Yes. Mark it as a priority in Settings and it gets more weekly sets.
- Does it track progress photos?
- Yes. Photos stay on your phone and never sync, and you can compare them side by side.
